Application filed February 14, 1910. Serial No. 543,670.

To (ZZZ whom it may concern Be it known that I, THOMAS LUND, a c1t1- Zenof the United States, residing at Beverly, in the county of Essex andState of Massachusetts, have invented certain I mprovements in Machinesfor Operating Upon Heels, of which the following description, inconnection with the accompanying drawings, is a specification, likereference characters on the drawings indicating like parts in theseveral figures.

This invention relates to certain improvements in mechanism for forminga bevel or lip at the breast end of heel blanks.

The invention is herein represented as embodied in an attachment toaheel oompressing machine of the type shown and described in UnitedStates Letters Patent No. 776,875, dated December 6, 1904, but is notlimited to use with machines of this type, and is shown as appliedthereto merely for purposes of illustration.

An important feature of the invention consists in providing, inconnection with a lip-cutting knife and its actuating mechanism, a heelblank support or carrier whlch is sustained by a vertically movingmember as, for instance, the reciprocating head of the heel compressingmachine, and is automatically moved thereby into position for receivinga heel blank and also into position for presenting the blank to theknife during the reciprocations of the head. Preferably, the heel blankcarrier is arranged to be moved into receiving position during thedownward movement of the reciprocating head, which occurs after thecompressing operation, so that the ejector of the heel compressingmachine will place the compressed blank on the carrier at the same timethat another blank is advanced in position to be acted upon by thecompressing dies, and as the reciprocating head rises a movement is alsoimparted to the carrier to locate the compressed blank in properposition for the operation thereon of the lip cutting knife. Preferably,also, the knife is so arranged for actuation through a moving part ofthe machine that the power which produces its cutting stroke is storedin a yielding element, as a spring or equivalent motor, by such movingpart, pre liminary to the operation of cutting the lip or bevel, and theknife is prevented from acting on the blank until the latter has beenmoved into proper position therefor by its carrier, whereupon the knifeis released by a suitable tripping device and cuts the corner from theblank.

An important feature of the invention accordingly consist in socombining a heel blank support or carrier and a lip-cutting knife with aheel compressing machine that a blank will be automatically delivered tothe carrier, the carrier actuated to position the blank in properrelation to the knife, and the knife actuated to bevel such blank,following the action of the dies thereon so that the operations ofcompressing the blanks and cutting the lips will be performedcontinuously upon a single machine in a very effective manner.

Another important feature of the invention consists in providingimproved means for removing the blank from its carrier at the completionof the lip-cutting operation. In the illustrated embodiment of theinvention this means comprises an ejector suitably supported in amovablemember which also supports an abutment or gage against which the breastof the heel blank is located when the blank is in position for operationthereon by the knife. The ejector slides freely in the movable member,and an elastic device, such as a spring, forms a connection between themovable member and the ejector, the movable member being caused totravel in a downward direction, through suitable actuating connectionswith the re ciprocating head as the latter moves up and while the blankcarrier is moving to locate a blank sustained thereon in the path of thelip-cutting knife. Preferably the ejector is provided with an arm orextension which comes in contact with a movable stop during its downwardmovement and holds back the ejector, thereby putting the elastic deviceunder tension. The downward movement of said member also serves tolocate the abutment or gage against the breast end of the blank as thecarrier is turned to bring said end into a substantially horizontalposition, whereby the blank is supported against the thrust of theknife. The movable stop is connected with the knife carrier, and whenthe knife is actuated to cut the corner from the blank the stop isremoved from engagement with the arm carried by the ejector and theejector is released and acts to force I the blank from its carrier.

Other important features of the invention, including improved details ofconstruction and combinations of parts, will be hereinafter moreparticularly described and claimed.

Y In the accompanying drawings, which illustrate a preferredconstruction embodying the principles of the invention; Figure 1illustrates, in vertical section, certain parts of a heel compressingmachine with the present improvements applied thereto, the

carrier being shown in receiving position,

with a heel blank thereon; Fig. 2 is a similar view showing the sameparts in another position; Fig. 3 is a rear elevation of the lip-'cuttlng mechanlsm shown in Fig. 1, somewhat enlarged; and Fig. 4 isaplan view of the heel blank carrier.

In the embodiment of the invention selected for illustration, 1indicates a part of the rigid frame of a heel compressing machine,'such,for instance as that disclosed inthe Letters Patent above referred to,and 2 indicates the reciprocating head thereof which will be supportedfor free movements in suitable guideways formed in the rigid frame 1.The head 2 carries suitable dies for imparting lateral compression to aheel blank as the head rises and meets a stationary die, which iscarried by the rigid portion of the frame 1 over the reciprocating headand serves to impart vertical compression to the blank. The crank shaft9, to which is imparted rotative movements by the main power shaft ofthe machlne, carries a crank 15 provided with a crank pin 16,

havingconnected'thereto a link 10 which is pivotally connected with themembers 11 and 12 of a toggle. The toggle member 12 is pivotallyconnected at "13 to a rigid part of ciprocating head 2, and .18indicates a heel 7 blank supporting carrieijherein shown as providedwith two laterally spaced, angularly disposed wings, 8, 8, which arerigid with the carrier, and connected through a pivot pin 7 with thebracket 5 so as to swing freely about said pin as a center. The wingsare shown as being provided with openings having cam-shaped 5 recessesor. slots 31, 32 and 33 within their edges which communicate with andare angularly disposed to each other, and pins 34, which may be providedwith antifriction rolls, extend oppositely from a rigid portion of theframe 50 into said recesses, said parts being so constructed andarranged that as the head 2 rises, the cam rolls will be caused to passfrom the slot 33 to the slot 31, and thence into the slot 32, which willturn the heel blank carrier from the position shown in Fig. 1, into thatshown in Fig. 2. Two oppositely movable heel blank gripping jaws 20, 20,are supported upon the carrier 18, each of said jaws being, as hereinshown, provided with a stem 19, which plays in a transverse bore formedin the carrier, each stem having formed thereon a rack 21, and saidracks are arranged upon opposite sides of and engage the teeth of apinion 22, which is pivotally supported upon the carrier. A spring 24,or other yielding device, is connected at one end to the carrier, and atits other end to one of the jaws and acts, through the connectionsdescribed, with a normal tendency to urge the jaws toward each other.The stems 19 have, as shown best in Fig. 4, extensions 26, which projectbeyond the sides of the carrier 18 and are provided with holes 27, andthe jaws have supporting base portions 28 apertured to receive slidablepins 29 which are provided with handles and may be placed in any of theseveral holes to adjust the distance between the jaws for heel blanks ofdifierent sizes. The outer or receiving ends of the jaws are slightlybeveled, as shown in Fig. 4, and the construction of the parts justdescribed is such that when the heel blank carrier occupies the positionshown in Fig. l and a blank is moved between the jaws 20 the jaws willyield to receive the blank which will be gripped be tween them and heldby the frictional engagement between the jaws and the sides of theblank, due to the action of the spring 24.

A rack bar 36, which is provided with a suitable number of teeth asshown, is supported from the bracket 5 so as to be reciprocated inunison with said bracket by the head 2. The bar 36 is preferablyprovided with suitable flanges which slide in guideways 38 formed in aframe 50, which is shown as connected with the main frame 1 of themachine by studs 40 which enter sockets in an upper part of the frame,and by a plate 52 which is bolted or otherwise suitably secured to aface portion 54, thereon. The rack 36 meshes with a pinion 42, which isshown as pivotally connected to the frame 50, and this pinion in turnmeshes with a rack 44 formed on or carried by a reciprocating block 46,which has flanges to slide in suitable guideways 48, in the sides of theframe 50. The lower part of the block 46 has a dove-tailed groove 56 toreceive the dove-tailed plate 58 which carries a projecting block 60,constituting a gage and abutment for the blank, and preferably formedwith a beveled rear surface, as shown. A clamping screw or bolt 62,having a thread to receive a nut thereon, passes through an aperture inthe base of the block 46 and a slot in the dove-tailed plate 58. By thisconstruction the gage or abutment 60 may be adjusted in a directionparallel with the breast line of a heel blank when the blank issustained in position against the abutment, to accord with theadjustments of the knife for producing different bevels; or suchabutment may be entirely removed from its supporting block and otherabutments of different sizes substituted therefor in order that themachine may accommodate heel blanks of varying lengths.

The frame 50 is shown as having two rigid screw-threaded studs 73projecting therefrom and said studs carry, respectively, the sleeves 75which rigidly support a knifecarrier guide 78, which is arranged at asuitable inclination to the breast line of a heel blank when sustainedin position against the abutment 60, as will appear from Figs. 1 and 2.It will thus be seen that the knife, which slides in said guide, mayremove the corner from the blank at an appropriate bevel or inclinationin the production of the lip. Each of the sleeves 75 is held adjustablyupon its supporting stud by nuts 76, which are in. threaded engagementwith the stud and bear against the opposite ends of the sleeve, wherebythe sleeves, and hence the knife guide, may be adjusted in order todetermine the amount of stock which the knife will remove from thecorner of the breast. The knife 80 projects rigidly from a knifecarrier, or stem 82, which slides in the guide 78 and is shown as beingformed or provided at its lower extremity with a sleeve 89, throughwhich passes a rod 94. At suitable points near the extremities of thisrod are attached the ends of two strong springs 95, whose upper oropposite ends may be secured to any rigid part of the frame, as forinstance to the studs 10%, which project therefrom. The sleeve 89 isshown as having a rigid toe 84- which extends at an angle to the knifecarrier, and a suitable detent 86 which is shown as being pivotallysupported from a pin 88 carried in perforated cars 90 which aresustained by the knife guide, is arranged in position to engage the toeand hold the knife retracted while the actuating springs 95 are undertension and ready to impart to the knife its cutting stroke. The detent86 is shown as having a lateral projection 98, and an arm 92, pivoted tothe rod 94: closely adjacent to the toe 84, has a finger 96 which isarranged to engage the projection 98 when the lower part of the arm iscaused to swing from the position shown in Fig. 1 to that shown in Fig.2 and move the detent out of engagement with the toe, thereby releasingthe knife and permitting the springs 95 to react and actuate the knife.The pivotally supported arm 92 is provided with a slot 100 whichreceives a pin or projection 102 rigid with the link 10, through whichsaid link imparts to the arm, at the proper times in each cycle ofoperations of the ma.- chine, first a downward movement for pulling theknife outwardly which permits the detent to engage the toe and hold theknife in readiness for action, and second a swinging movement fortripping the knife. The manner in which these operations are performedwill be more fully described hereinafter.

The numeral 64 indicates the ejector for removing blanks from thecarrier 18 at the completion of the lip-cutting operation. The ejectoris supported for free vertical sliding movements in the block 46, and isalso arranged to slide through a slot pro vided therefor in the abutmentor gage 60,

and is shown as having a laterally extending arm 66. A yielding device,herein shown as a spring 68, is connected at one end by a screw or likefastening to the arm 66, and at its opposite end by a similar fastening71 to the block 46, and acts with a normal tendency to hold theblanlrengag ing end of the ejector projected a suitable distance beyondthe lower surface of the abutment 60, as shown in Figs. 1 and 8. Abell-crank lever 106 is fulcrumed to a pin 108 carried by the frame 50and has its upper end so formed as to constitute a stop 105, which isarranged to intersect the path of movement of the arm 66 as the ejectorismoved down to position the abutment against a blank sustained upon thecarrier. The lower arm of this lever is shown as having a sleevedextension 110 which is pivotally connected with one end of a link 1 14:by a pin 112, the opposite end of this link having pivotal connectionwith the knife carrier through a pin 116, which projects from thecarrier. With this construction,

prior to the operation of the knife and when it occupies the positionshown in Fig. 1, the stop 105 will lie immediately below the arm 66. Asthe block 46 is moved down the stop will engage and arrest the movementof the arm and hold back the ejector, and the spring 68 will be putunder tension. When the knife is released and moves under the force ofits springs 95 to cut the corner from the blank the describedconnections between the knife and the stop 105 will remove said stopfrom engagement with the arm 66, and the spring 68 will force theejector against the blank to eject the blank from the carrier.

'With the several parts of the machine occupying the positions shown inFig. 1, the reciprocating head 2 has been lowered, following theoperation of compressing a blank, and the blank has been placed by theejectorof the heel-compressing machine or blank feeding device upon thecarrier 18 i and between the jaws 20, and is gripped I throw, when themachine starts, the link is moved in a direction to straighten th toggleand raise thev reciprocating head for compressing a blank between thedies, which moves upward also the heel blank carrier and its blank, thecarrier being radually turned as it rises through the action of the camslots and roll to present the blank with its breast horizontal, as shownin Fig. 2. As the head 2 rises the rack bar 36 is caused to rotate thepinion -12 which imparts a downward movement to the block 46, cansmg theheel. blank abutment and gage 60 to meet the breast of the blank as itrises, so as to act as a stop for the blank andsupport it against thethrust of the knife, and the arm of the ejector engages the stop 105 andis held back while the spring '68 is stretched and rendered in conditionto act. As the link l0 is moved from the position shown in Fig. 1 tothat shown in Fig. 9.,the pin 102 carried thereby acts to swing the arm92 over, and substantially at the moment when the crank has reached theinward limit of its throw the finger 96 pushes the detent over the edgeof the toe 8 1 and the knife is released and cuts the corner from theblank. The described connections between the knife carrier and the stop105 are so-constructed and arranged that the stop is moved from beneaththe armof the ejector to release it at or about the same time that theknife completes its cutting stroke, so that the blank is ejected fromthe carrier immediately after the lip-cutting operation. The continuedmovement of the crank will cause the toggle members to lower thereciprocating head, during which the heel blank carrier will be restoredto its receiving position as shown in Fig. 1, and the movements down andrearwardly of the link 10 will cause the pin 10:2 to engage theextremity of the slot 100 and pull down the knife carrier and knife, andalso rock the lower end of the arm 9:2 and move the finger 36 out ofcontact with the detent 86, thus permitting the detent to fall bygravity in front of the toe 8% as the toe passes beyond the end of thedetent. The parts will then again 00- cupy the positions shown in Fig.1, and the described cycle of operations may be repeated as often as thereciprocating head I claim as new and desire to secure by Letters Patentof the United States is:
